AR_GET_TIMERCNTL
CEI_UINT32 ar_get_timercntl (CEI_INT16 board);
The ARINC interface is programmed to maintain an elapsed time count in
“ticks”. This routine returns the number of ticks that have occurred since
the timer was initialized (see AR_LOADSLV) or since the counter was
reset to zero (see AR_RESET_TIMERCNT). This value determines if a
specific time interval has passed to help in the timed re-transmission of
ARINC data. The resolution of a tick is programmable through the
routine AR_SET_TIMERRATE. This routine is identical to
AR_GET_TIMERCNT except that it returns 32 bits instead of 16.
The number of timer ticks (32 bits wide).
board (input) board number from which to read the timer
count.
